Start at 5:30 not sure this makes sense but its his explanation. Basically for use on a service utility side and and load side. Dual or multiple use such as a neutral or an EGC depending on application re-identify with appropriate color.

Whats with URD having a yellow neutral? Or people pulling yellow THHN or XHHW in their service conductors?
LOL! when I read the title - reminded me of a mentor 50 years ago telling me about 3 phase trouble shooting: - ' you can tell if there are a lot of harmonics if the white wire is brown or yellow'

There is nothing I know of in the NESC that talks about color codes much less yellow for a Neutral.
Seems like they just picked yellow.
They should just use white or light grey, the code used to refer to 'natural grey' as that was the color of the untreated cloth covering.

I doubt any linemen would complain about yellow going away as a neutral.
